7.1 Local HART connection
7.1.1 As a Varec tank gauging instrument
The 4532 ATC has been developed and designated primarily to work with the Varec tank
gauging host instruments 4590 TSM or 6000 Series Servo Tank Gauge.
Temperature information is transmitted on a two wire i.s HART loop to the host
instrument.
Since both the 4590 TSM and 6000 Series Servo Tank Gauge have a pre-configured
menu for 453x average temperature devices functionality as default, simple wiring to
the 4532 ATC will complete the initial setup for the 4532 ATC.
7.1.2 As a standalone generic HART instrument
The 4532 ATC is a HART foundation registered intrinsically safe loop powered device.
The 4532 ATC provides four basic types of data as standard and parameter information
via HART protocol, command 3. Configuration to host communication can be performed
by a HC (Hand Communicator) or the Varec ToF field service tool to set a specific HART
address.

7.2 Device set up: 4590 TSM
Connect the loop powered HART communication cable from the 4590 TSM (intrinsically
safe side compartment) to the 4532 ATC.
Since the 4590 TSM has been designed to recognize the 4532 ATC as a specific Varec
HART instrument, set up is easy.
7.2.1 HART scanner
After the physical cabling between the 4532 ATC and the 4590 TSM is complete, scan
all connected loop powered HART devices by activating "HART SCAN" on the version 1.x
4590 TSM. The version 2.x 4590 TSM continually scans the HART bus and will
automatically detect the 4532 ATC when it is connected.
Caution! Not all 4590 TSM have fully accessible compatibility to recognize the 4532 ATC.
Consult with your Varec representative to cross check the software and hardware
version of the 4590 TSM.
